## Summary
- Fix plan_mode questionnaire test to use `getByText` for Base UI Radio
components (hidden inputs can't be clicked with
`getByRole`/`getByLabel`)
- Update chat_history tests for chronological order (oldest first)
- Add `clearChatInput()` and `openChatHistoryMenu()` helpers with
`toPass()` retry logic for reliable Lexical editor interactions
- Add `Timeout.SHORT` constant for quick retries
- Update AGENTS.md with Lexical editor and Base UI Radio testing tips

## Test plan
- [x] `npm run e2e e2e-tests/plan_mode.spec.ts` passes
- [x] `npm run e2e e2e-tests/chat_history.spec.ts` passes
- [x] `npm test` passes

<!-- CURSOR_SUMMARY -->

> [!NOTE]
> **Low Risk**
> Changes are confined to E2E tests, developer docs, and pre-commit
tooling; product/runtime logic is untouched, with minimal risk beyond
potential CI formatting or test expectation drift.
> 
> **Overview**
> Stabilizes Playwright E2E coverage around plan mode and chat history
by switching Base UI Radio selection to clicking visible label text and
by adding Lexical-safe input helpers (`clearChatInput`,
`openChatHistoryMenu`) with short `toPass()` retries.
> 
> Updates chat history assertions to match **chronological ordering**
(oldest-first) and refreshes related snapshots/docs. Also tightens
pre-commit formatting via `lint-staged` (limits `oxfmt` to a narrower
glob) and simplifies the Husky `pre-commit` hook to only run
`lint-staged`.

## Summary by cubic
Fixes flaky E2E tests for plan mode and chat history by using reliable
selectors and Lexical-safe helpers. Radios can be selected via visible
labels, and chat history tests now match chronological order.

- **Bug Fixes**
- Plan mode: select Base UI Radio by clicking label text with getByText.
- Chat history: update tests for oldest-first order and default
selection behavior.
- Helpers and docs: add clearChatInput/openChatHistoryMenu with toPass
retries and Timeout.SHORT; update AGENTS.md with Lexical and Base UI
tips.
  - Pre-commit: remove YAML from oxfmt to fix hook failures.
